Java Security

Hi

Is there someone who can help me to solve this problem, I try to run this program to connect to a server using https (https:\\www.xxx.xxxxx.xx\servlet). To reach this server I have pass a proxy inside our network. Is this Exception related to proxy or is it some wrong coding in my program:

Exception in thread "main" java.util.NoSuchElementException
at java.util.StringTokenizer.nextToken(StringTokenizer.java:232)
at sun.net.www.protocol.http.HttpURLConnection.doTunneling(HttpURLConnection.java:762)
at sun.net.www.protocol.https.AbstractDelegateHttpsURLConnection.connect(DashoA6275)
at sun.net.www.protocol.http.HttpURLConnection.getOutputStream(HttpURLConnection.java:510)
at sun.net.www.protocol.https.HttpsURLConnectionImpl.getOutputStream(DashoA6275)
at NetworkAccess.main(NetworkAccess.java:143)
